A mentor, teacher or guide will not only teach you the basics in the order of importance and how you should know it, but will also share with you their experience, and that can be very invaluable.
Some early mistakes in trading are capable of ending your trading career. A mentor, teacher, or guide can help you avoid some of these major pitfalls.
I totally agree with what you say that learning trade is too difficult to do, because it is not really easy to learn. If those who studied theory regarding the so-called trading course still have difficulty when it comes to proper execution, how much more so when you just study it without execution.
Although, it is not bad to be taught, but only as far as guidelines can be done by mentors, because they will not teach you the proper execution itself for sure.
In the end, you or we will still discover our skills to tell you frankly.
The only cons when you do have a mentor is that you will really be needing to pay up some extra and also you will really be that somewhat dependent when you are really that having that learning curve.
It wont really be that a problem as long you do make yourself that learn along the way or whatever the way or path you will be taking, the important thing on here is that you do get that specific skills
on which you will be the ones will be enhancing it with your real time experiences towards this unpredictable market.
